I1VIPRQVED APPARATUS FOR EXTRACTING'ESSENGES, Ecc.

The Schedule l:referred to in these Letters Patent and making part of the name.

To all whom it may concern:

Be it known that I, GIDEON BAN'rz, of the city and county of Frederick, and State of Maryland, have invented a new and improved Apparatus for Extracting Essences, and for other purposes; and I do hereby decla're that the following is a full, clear, and exact deseription of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a longitudinal vertical section through line a: of g. 2.

'Figure 2 is a plan.

The object of this invention is to provide an appa ratus by which essences can be extracted more perfectly and expeditiously than heretofore, and which shall necessitatethe .incurring of but little expense in its construction and practical operation.

The' apparatus thus constructed is of such a form and character that it may be conveniently employed' for manyv other purposes.4 j l V The main principle involved in my improved apparatus is the peculiar manner of applying the boiling water to' the materials which are to be subjected toits operation, such materials not only lying in a vessel of boiling water, but at the same time being subjected to the powerful action of several streams of water, which, elevated at the sides of the apparatus throughthe action of the heatand thesteam, are thrown inward toward the centre of the Yvessel with great force.

In this manner a constant currentl of boiling Water is maintained in the vessel, the fluid' passing up at its sides and being thrown inward from around its top, thence flowing downward and outward toits sides again, where it is again elevated and dashed in toward the centre of the vessel.

'Ihe action of the boiling water, when thus dashed upon the materials with considerable force, and when accompanied by the action of atmospheric air, which is carried down by the jets into the mass of water and among the materials to be acted on, is much moreenergetic and thorough than when applied Ain the usual way.

In the drawings, the red lines indicate a boiler in which the apparatus is to be used. The black lines indicate the apparatus itself.

A indicates a plate, of sheet-metal, or other suitable material, to the `upper side of which are attached several vertical tapering tubes, B B, which support a continuous horizontal tube, C, the latter being provided with a series ofV openings, c c, around its inner wall, and the whole being soconstructedand connected that fluids can pass into the tubesB B from the under side of plate A, thence into pipe O, and thence, through the openings c c, into the' space enclosed by pipe C, falling back upon the upper side of plate A.

Plate A. is also provided with a circular rim, or flange, D, around its perimeter, and with a ange, E, smaller Y in size, around its centre, both flanges extending downward. The apparatus rests on the outer flange, which sits on the bottom ofthe enclosing boiler.

When in this position, the inner dange does not come quite down to the bottom-of the boiler, and the Plate A is provided withv several openings, ll I I, in-

side of the flange E, and communicating between the spaces F and J. A

Each opening communicates with space F through a short tube, t', which, being attached to the under side ofpplate A, so as to surround the openings I, extends about half way to the bottom of space F.

This constitutes the apparatus as complete and ready for use.

` Its operation is as follows; It is placed within the boiler, in vthe manner represented ,in fig. 1, and, the latter being partially lled with water, is subjected to a lively heat. The materials to be subjected.- to its operation are placed upon the foraminous cover h. As

soon as the water begins to boil, the steam in space- G, above the lower end b of thev vertical pipes, forces the boiling fluid up through the pipes into the tube O, and thence through the openings c c, driving it with greatforce upon and against the material below. Thence the waterV passes down through `plateh and tubes i i, and under fiange E to space G, whence it started.

This apparatus will operate with considerable suca cess without the parts b, E, and i, as I have 'satisfied myself by experiment, but theffull perfection of the instrument absolutely requires these parts, in order to afford a steam-space above the water, under plate A, in which the steam generated under the plate shall collect, so as to force the water up through the pipes and dash it upon the' materials in a lively and effective' Without the steam-spaces, the circulation nf the i luids will take place, `but in a slow and uncertain manclaim any of the many washing-machines and dyeingapparatus, which resemble my apparatusfor extracting essences; but having thns'described my invention,
